If the size is very important for you, check the photo of the box first. The description by Amazon lists these as 1-1/4, however the box actually lists 1-1/16.Even then, really the usable size is closer to just 1".We needed super large clips at the office, and measured that 1-1/4 would be just perfect, however with the actual usable bit measuring in at 1", we're having some problems making them work.Granted, they do work great, but the item description was misleading online, and the actual stated capacity is also stretching it a little.Durability is great as usual, though unusual warping may occur due to the larger size. Harder to open to the full 1" size.
